No puede obtener sus datos de muestra de los datos "sin procesar" que publicó. Realicé ingeniería inversa de los datos sin procesar de sus datos de muestra en la subconsulta ORIGINALDATA, luego se me ocurrió esta solución:
WITH SAMPLEDATA (CYCLEID,GROUPID,GROUPNAME,COL1,COL2,COL3,COL4,COL5,COL6,COL7)

SELECT 1,7669,'000000261','GAS',NULL,NULL,NULL,'1',NULL,'00' FROM DUAL
